CAR COU PLING ATTACH [Vi EN T.

SPECIFICATION forming part of Letters Patent No. 663,793, dated December 11, 1900.

Application filed May 29, 1900.

T ctZZ whmn it may concern:

Be it known that LTHOMAS P. SMYTH,a citizen of the United States, and a resident of Pocatello, in the county of Bannock and State of Idaho, have invented a new and Improved Car-Coupler Attachment, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide means for preventing the fall of a coupler should it for any reason become detached from the car on which it is mounted and also to prevent losing the knuckle or breaking the coupler owing to the breakage of the pivotpin on which is mounted the jaw of the coupler. Ordinarily both of these disadvantages frequently occur, and my invention comprehends a simple attachment to a coupler which will prevent the falling of the coupler and also the disadvantageous results of the breakage of the pivot-pin of the jaw.

This specification is the disclosure of one form of the invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of a coupler having my invention applied thereto in the course of the construction. Fig. 2 is a side view of the same. Fig. 3 is a side view of a coupler having my improvement applied thereto subsequent to its manufacture. Fig. 4 is a sectional view showing the parts at the lower end of the pivot-pin in Figs. 1 and 2. Fig. 5 is a plan view of two engaged couplers with my improvements applied, as illus trated in Fig. 3. Fig. 6 is a front View of the construction shown in Fig. 3, and Fig. 7 is a detail section of the parts at the lower end of the pivot-pin in Figs. 3, 5, and 6.

Referring to Figs. 1, 2, and 4, the coupler a is of the usual construction, having a jaw 79, mounted on a pivot-pin 0. Cast integrally with the coupler and extending across the same at its under side is a U-shaped hanger 6?, one end of which terminates directly at the lower end of the pivot-pin c and the other Serial ITO-18,394. (No model.)

cl, which end is formed with a collard, lying directly under the coupler and through which collar the reduced end 0 of the pin 0 passes.

Assuming that the couplers are connected in the usual manner, should one of the couplers become detached from its car owing to an accident of any sort it will fall upon the hanger d of the other coupler and will be sustained thereby. It will not be permitted to fall upon the track. Further, should. the pin 0 become broken, as is frequently the case in railway operations, the lower part of the pin will be sustained on the collar cl of the hanger d, and the pin will therefore be kept intact, and the fracture of the coupler which generally takes place as an incident of the breaking of the pivot-pin will be prevented.

When the invention is applied to couplers already constructed, the hanger d has one end passed through openings formed in the lower ribs to of the coupler and fastened therein by a nut d as shown. The hanger (1 passes across thecoupler and has formed at its opposite end a collar (1 through which the lower end 0 of the pivot-pin c of the jaw b is passed and fastened by a cotter-pin 0 (See Fig. 7.) This arrangement operates in exactly the same manner as the arrangement shown in Figs. 1, 2, and 4, and it differs therefrom only in that the hanger d is cast with the coupler and the hanger d is fastened thereto, as described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A coupler, having a rigid hanger eX- tending under the same, the hanger being arranged to prevent the falling of a mating coupler, and a support adapted to receive the lower end of the pivot-pin of the coupler-jaw to prevent the fall of said pin when it becomes fractured, the said support being connected with the hanger.

2. A coupler, having a hanger rigidly con- In testimony whereof I have signed my nected therewith, the said hanger being carname to this specification in the presence of ried at the under side of the coupler and extwo subscribing witnesses.

tending across it, and a collar integrally con- THOMAS P. SMYTH.
